For a start, a 3-litre pot is far too small for a permanent home. You
will need to obtain really large planters or tube. If you can get a
pair that fit into a corner and flat against the wall, all the better.
The plant grows to about 15 feet high, so it will have a substantial
root structure. I do not see them as good tub candidates, I am afraid.
